Close to three inches of rain fell in Boston since Thursday, more than in the entire month of June. Elsewhere in New England, rainfall has been generally 1-2 inches, with hardly any toward the Canadian border.

The same front that ended the heat wave is now stalled just east and south, with wave after wave of low pressure passing by the coastline. Think of this as a weak summertime Nor'easter. There is a gale warning off shore for northeast winds of 20-30 mph and building seas.

Overnight, expect cloudy skies with spotty downpours resulting in localized flash flooding once again, other times just fog and drizzle as an area of low pressure passes south of the region. Lows in the 50s.

Despite warnings against consumer firework use, the National Safety Council has outlined safety guidelines for people to follow if they choose to engage with them. Here are the following questions you should be asking yourself before using consumer fireworks.

For fireworks, low clouds and fog may limit visibility to the point of postponing for many. The best nights will be Sunday and Monday.
